Missouri City Housing Stock
Half the homes in Missouri City were built before 1993 (Census ACS median), so the typical house is about 33 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 81.4% of occupied homes, roughly 22,000 households. The median home value is $281,600, and median household income is $96,746. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 3 hail days and 11 days with damaging thunderstorm winds in Fort Bend County. The largest hail reported was 2.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Fort Bend County also had 2 tornado days in that period.
